In 2009 she made a cover of Amy Winehouse' "Blonde Trick" and, after a friend posted the song into MySpace, the production team The Cataracs noticed it and contacted Dev.[1] To Fashion Indie Magazine she said: "I decided to put up this song on MySpace. [...] it was basically a "diss track" and I didn't expect anything out of it. It was just to make me feel good like how music usually do but Niles [of the Cataracs] came across to my page and was really into my voice and they kind of got me into singing and opened up my eyes to business opportunities".[3] She dropped out of college in her first year to pursue her singing career and was then signed by the Los Angeles-based record label and management team, Indie-Pop, who also discovered The Cataracs. Six months later, Dev and The Cataracs' song "2Nite" began to gain exposure on the radio, the television channel MtvU and the BillboardHot Dance Airplay chart.[1] In 2009, Dev moved to Los Angeles to produce music with the Cataracs and work directly with Indie-Pop.[2]

In 2010, the Cataracs produced "Like a G6" with Far East Movement and decided to use a verse from Dev's single "Booty Bounce" as the chorus.[4] The two songs were made in the same summer, at the time where Dev and the Cataracs "were grinding it out in the studio pretty tough together," making a couple of "simplistic random tracks."[3] "Like a G6", which features Far East Movement and Dev, was released in April 2010, and reached number one on the US Billboard Hot 100 chart.[5] The song went on to sell over four million downloads in the US.[6] In August 2010, a music video was made for "Booty Bounce" directed by Ethan Lader, and uploaded it onto YouTube, where it has generated over twenty million views.[4][7] In October 2010, Dev was signed to Universal Republic and her first official single, "Bass Down Low", was serviced to rhythmic radio stations in November.[4][8] It was released digitally in select territories on December 6, 2010 and one day later in the United States.[9][10] The song reached sixty one on the Billboard Hot 100 chart and number two on the Heatseekers Songs chart.[11] In Canada, the song peaked at number thirty five in its fifth week on the Canadian Hot 100 chart.

Dev's electro style and "sing-talk" vocal style have been compared to fellow pop singer Kesha.[26] Dev responded to this, saying, "I'm confident enough in what I do that people will see me for who I am ... I get why people compare us but once people see me live they won't connect us as much."[7] While comparing her to Kesha, Idolator wrote that "Dev's beats come off a bit more mellow and her songs a little bit more electro than pop."[26] In response to being compared to both Kesha and Uffie, Dev said, "I just feel that I have a lot more to say and the ability to have an eclectic sound, I'm not bashing either artist, but I'm going to be able to give you a little bit more than what you've heard on those records. When my album comes out, hopefully I won't have to hear another reference or comparison."[3] Much of Dev's music is inspired by rap music, as she believes that fans respond to "pop music but with rap roots". She said, "I've always been into hip-hop. Eminem changed my life when I was younger."[7]The Hollywood Reporter compared her "futuristic" and "pulsing" sound to underground electroclash musicians Peaches and Yelle.[7] Dev's musical genres have been cited as electro-crunk[27] and electropop.[7][26]
